Observation was held from Monday-Friday, 06.00-10.00 AM and 1.30-5.00 PM during bright day or if it is not raining. Identified wild birds were analized using Shannon-Wienner index and I.P.A count. There were 64 species and 28 families of wild birds found. Shannon-Wienner index value for morning and afternoon obsevation are 2.66 and 2.62 which means the wild birds are sufficiently diversed. There were 17 new records found in this research. The different number and diversity of wild birds compare to previous observation may due to human presence and different bird observation methods used. Streptopelia chinensis has the highest density value for morning and afternoon observation, 2.77 and 3.28. Human presence, bird activity and environmental factors caused the differentiation of density value. Most wild birds have distribution area from Sumatera, Java, Bali and Borneo.
